COMPOSITION CARRIER OR HOLDER.

Application filed September 10, 1915.

i a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Composition Carriers or Holders, of which the following is a full, clear, and exact description.

My invention relates to certain new and useful improvements in holders or carriers for composition Composition may consist of regular type, linotype, stereotype, electro-type, monotype, plates or dies.

As an explanation of the objects of my invention, and to illustrate one use of my composition carrier or holder, I will refer to the manufacture of envelope. In the manufacture of envelops, it is customary to print corner cards or the senders name and address on the corner of the envelops. The type for this printing may be set up on a linotype machine and then locked in a slug holder which securely holds the slugs while the printing operation is carried out. lVith this sort of work, it is necessary to frequently change the type because small lots of envelops are printed for different persons and ywith corresponding dierent corner cards. In former machines, the type have been locked in place by using a wrench, screw driver or other tool. This method is satisfactory on machines where the slug holder is easily accessible, but with certain types of machines, particularly those of the continuous rotary type, the slug holder is necessarily locatedin an inaccessible part of the machine and the operation of changing composition becomes a difficult, dangerous and time consuming operation. The operator must reach into the center or other inaccessible'part of the machine through a closely arranged set of gears and rollers in order to reach the type. This, in addition, may be the cause of accidents if the machine accidentally starts, and nearly always results in smearing the hands and clothing of the operator with grease and ink, which is also likely to come into Contact with the product, thereby destroying it.

To the elimination of these defects and for other ends I have devised my improved composition holder, which is adapted to be bodily withdrawn to the outside of the machine frame` where the composition is accessible and easily and safely replaced.

Specification of Letters Patent.

Patented I une 20, 1916.

serial No. 49,882.

With such a construction the composition is always placed in a correct position in the holder and the cleaning ofthe holder and type or other composition is facilitated. In addition, the time of changing composition 1s reduced and accidents to the operator are prevented.

My improved construction also eliminates the use of a wrench or other tool for changing composition, since the means for withdrawing the holder or carrier from the machine is also used for releasing the composition or type slugs.

It will be understood that my invention is not limited to envelop machinery, since the improved holders are equally valuable in other printing machines.

In the drawings, Figure 1 shows a side View of the composition. The carrier is in the form of a mandrel and is shown removed from the printing machine and the driving shaft is shown broken off, Fig. 2 is a plan view of the mandrel. This view shows the frame of the printing machine, and the drive gear is also shown. The side frames of the machine are shown closer together than the actual machine on account of lack of room. The mandrel in this view is shown withdrawn from the frame. Fig. 3 shows an end view of the mandrel and the handle therefor. This view also shows in a diagrammatic manner some of the adjacent parts which surround the mandrel and necessitate the axial shifting of the mandrel in replacing the type. Fig. 4 shows a side view of one of the linotype slugs. Fig. 5 shows an end view of the slug shown in Fig. 4.

In more detail, referring particularly to Fig. 3, 10 and 11 are the paper feeding rolls. The paper advances along the dotted line and `passes between the impression platen roll 13 and the mandrel shown by the dotted line 14. The type carried by this mandrel are inked by contact with ink roll 15, which in turn is inked by doctor roll 16, which con tacts withV fountain roll 17 revolving in ink in the fountain 18. The mandrel impression roll and feeding rolls may be driven by suitable gearing not shown in this figure. This figure illustrates the difficulty of re placing linotype slugs on the mandrel when it is remembered that the printing position is a considerable distance from the edges of rolls 10-11 and 21.

view.

filsv In Fig. 1, thermandrel isshown in a side tensions and 22 shown -in dotted lines. Extension 22 and body portion 14 are connected byV a taper 23. Over extension 22 is a sleeve 24, which `sleeve is tapered at one end to correspondtoV taper 23. Sleeve 24 is pinned to extension 22 by pin 25. Extension 22 projects beyond sleeve 24 as shown at 26. It isv this portion 26 which iorms the journal forl the mandrel when it is in in position. When in lsuch position, 26 titsV into bearing 27 of side frame 28 (shown in` Fig. 2). `A splined drivingshaft 29is rigidly Connected with parts 22 and 26 and extends a considerable vdistance beyond 26. This splined shaft extends through the driving gear'30, which is slotted to receive the spline and' a collar 31 on the end of the shaft prevents vthe shaft from being entirely withdrawn from the gear.

In this way the shaft and connecting mandrel are always keptin Y the sameangular relation with the gear,re`

gardless of whether the mandrel is withdrawn or in printingA position in the side frames. p length of shaft 29 (shown'broken off in'Fig. 2) is dependent upon'the distance that the mandrel is! withdrawn from the machine and that whenA the mandrel is withdrawn that it -isl supported by theshaft 29 coperating with gearl 3Q, which is journaled upon jframef28 in anyedesirable manner.

Mandrel'loc'z'ng device-Upon extension N620/Vis a bearingrsleeve21, which VVbearing sleeve is of such size that it will fit closely the bearing 32 inthe left hand frame 28a of the machine, when the mandrel isin in position. To facilitate the entry of sleeve.

21 into bearing 32 when the mandrel is being returned to in position, the sleeve `21V is made slightlyA tapering, asvshowny at 33. The oppositel end of bearing sleeve is enlarged to form aithrust shoulder 34. This portion of the sleeve also `forms, part of the clamping device as willhereafter be explained. Extension 20 of therbody of themandrel has Y secured to itsend by a set screw a collar 35,

which keeps bearing'sleeve l21 from sliding axially on; the said extension. Two posts 36 extend outwardly from part 34 of sleeve 21 and support a pinp37, which forms a pivotal support for a handle 38which'handle is spaced centrally between the posts by the bosses 39;j(see 3). The posts 36 are 1 Y It consistsv of the body portion 14` which has extending from each Vend the ex- It willbe understood that the.

Vyond theend of this type slug.

V38 is turned until the notch 40 is in line with the head 42 of the screw 41. Then the mandrel is pushed in. To lock the mandrel in in position, the handle 38 is given a counterclockwise motion. This brings a. cam edge 43 (shown in Figs. 2 and 3) into Contact with the head 42 of screw 41 and securely holds Vthe mandrel from outward movement.

Linotype slug holding mechanism-As previously explained, this mandrel or slug carrier is adapted to carry a number of linotyp'e slugs. These are of the shape shown in Figs. 4 and 5. They are tapered toward the base, as shown in Fig. 5, and at each end the corners are tapered at 45 and 46. The slug itself is indicated by the character 47. The base of the slug is indicated by character 48 and the ends by 49 and 50, respectively. To carry the slugs a slot is cut in the mandrel of a depth suliicient t0 bring the top of the type at the proper height 'for printing. The bottom of the slot in the mandrel 14 is shown by the dotted lines48n and 48b in Fig. 1. It will be understood that the bottom of the slot is curved t0 correspond with the periphery of the mandrel to properly aline the type slugs. The slugs 47 are placed inthe slot completely filling the width of the slot as shown in Fig. 2. The tapered ends 46 of the slugs engage the tapered edge 23 of sleeve 24. This tapered edge. forms a camming abutment and coperates with other devices to secure the slugs in the slot. The end of the slot opposite tapered edge 23 is extended somewhat be- This portion of the slot is also deepened somewhat, as shown at 51. Pivotallymounted on the countersunk screw 5 2 and extending down into the portion 51 of the slot is a camming Vmember 53. This camming member has a tapered nose 54, the taper corresponding to the taper 45 of the type slugs 47 and being adapted to engage over the tapered end of the slugs and hold them tightly against the cam abutment 23 at the opposite end of the slot. To hold the camming member 53 in engagement with the tapered ends 45 ot' slugs 47 ,4I providea plunger 55 which is pressed against the upper part of said camming member by means of a spring 56. Both spring 56 and plunger 55 are mounted in a, cage 57 which is secured by a set screwv in position in the mandrel.

Slug releasing mecLanz'sm.-In order to vrelease theslugs 47, a plunger 58 is provided. This plunger 58 has free axial movement ina hole which is centrally located in the mandrel. One end of this plunger 58 contacts with the camming member 53 at a point below the pivotal support 52. It will be seen that by pressing inward on the plunger the camming member will be rocked in a counterclockwise direction,

thereby compressing spring 56 and moving the camming nose 51l to a position Where it Will be free from the type slugs. The slugs can then be lifted from the` slot and new slugs inserted.v To provide for easy access to the slugs When replacing them, the mandrel is notched at 59 on both sides of the slot.

For pressing the plunger 5S inward, I utilize the handle 38. When it is desired to release the type slugs, a latch 60 is first released from engagement With a hook 61 on the shoulder 34. This latch 60 is normally held in engagement with hook 6l by means of a spring, the latch being pivotally mounted at 62 on handle 38; a plunger' 63 is longitudinally mounted in the handle 33. By pressing upward on the button on the end oi plunger 63, the plunger Will rock latch 62 in a clockwise direction and release it from engagement with the hook 61. Thereafter the handle 38 can be rocked in a clockwise direction about its pivot 37. Pivot 37 being located in posts 36 belovv the center line of the mandrel, a nose 64 projecting upwardly from handle 38 is adapted to force plunger 58 inwardly and release the slugs 47 in the manner previously explained.

It will be seen that my improved mandrel is particularly adapted to carry linotypeslugs for contact With an impression platen and that the inandred can be Withdrawn from the frame of the machine When it is desired to replace, clean, or otherwise .treat the slugs or other composition. The improved mandrel also provides a simple means of locking and releasing the slugs.

For purposes of illustration, I have merely shown my composition carrier in connection with linotype slugs, but it Will be under'- stood that other composition may be used as well. For example, if dies were used in place of the linotype slugs it would merely be necessary to provide the dies with tapered corners like corners 45 and 4-6 of the linotype slugs.

It is to be understood that I do not limit myseltI to the precise embodiment shown and described. lhat I claim as my invention is particularly pointed out in the appended claims.
